is this right?

Continuing to try and understand my clutch on my 2000 3cyl gas (single stage). I am posting 2 photos. One with the clutch arm back is in position where resistance to the clutch starts. The other is of the arm swung forward. There is 2 1/4 movement before clutch resistance. Someone mentioned it might be installed wrong? WOuld this be a clue? It is working fine now, but I have no adjustment left on the rod. Clutch is supposed to be new (100 hrs)

Did you not see my reply in your other message [u:17ed5eecae][b:17ed5eecae]here?[/b:17ed5eecae][/u:17ed5eecae]


Here's another explanation again with some pics.
When you press the clutch pedal down, the release bearing carrier (#5 or 5A in the second pic below) slides forward along the nose cone of the transmission front bearing carrier (#3 in the third pic below) until the bearing contacts the release levers of the PPA. That is your clutch pedal free play. Further pressing the pedal down pushes on the release levers, disengaging the clutch disk.

When you have the clutch pedal rod disconnected and swing the release shaft (#10 in the first pic below) forward, this rotates the release shaft fork (#15 in the first pic below) towards the rear either away from or with the release bearing carrier. Now when swinging the release shaft backwards, you are moving the release shaft fork forward towards or with the release bearing carrier. At some point you take up all the slack you had just previously introduced until the return springs begin to stretch, and you can "feel" a bit of resistance as these springs stretch. [u:17ed5eecae][i:17ed5eecae][b:17ed5eecae]That is the "2 1/4 movement before clutch resistance" you ask about.[/b:17ed5eecae][/i:17ed5eecae][/u:17ed5eecae] If you continue to push the release shaft it eventually contacts the release levers of the PPA again.

As I said in my reply to your other message, under normal operation the release bearing carrier doesn't travel that far back, no need to. It only goes back until the clutch pedal is all the way to the top. Then the little distance that's left before contacting the release levers is your clutch pedal free play.

Good explanation from jim. I'll add that as the clutch disk wears the pressure plate moves forward, causing the fingers to move to the rear which reduces the free play. That's when you have to readjust. You would do that by lengthening the rod. You're OK, don't overthink it.
 
Thanks Jim and Mike. Jim the diagram was helpful. Mike you are right about overthinking. And bacward thinking. I was worried since I was at the end of the adjustment I
was in trouble, but if the rod only gets adjusted longer as the clutch wears I am in good shape. I still get a little bit of gear grind if I am in a hurry, but I am not,
and I don't have any need for fast shifting. I am 70. I doubt I can wear it out in my useful years.
